Hi there. I've used the Ultrascope software and I kinda feel I've not gained any special feature. The video output is laggy, more or less 2 fps. I think that in order to obtain more functionalities from the oscilloscope, you have to write your own Labview software using VISA drivers. The Ultrascope software is a bit limited, IMHO.
If you want to capture screens and record waveforms, a USB memory in the front can help.
